scription. Among thicknesses for utilization indifferent ways.

1 forming the article; Fi 3 shows'the completed article; Fig. '4 1s a sectional view gromet constructed and arranged in accordance with the present invention as sealing" the bolt-hole formed in said structure]; Fig. 5 is a sectional view showing a construction employ-in a hand-hole a coverin cap therefor, i0 b lts for structurally uniting the same, and ajgromet forsealing the handhole and the lb'olt-holeslsurroundinjg thesame; Fig. 6 is a view of. a gromet constructed for service such as indicated in Fig. 5. Fig. 7 is a side elevation of two sections of pipe, thefjoint between which is 1 and fparticularly in Fig; 1 thereof, a' skein wrapped to form' an open-centered coil 12.

'fiber is lightly twisted upon itself and Whenthe coil 12'is deemed. to have sufficient tinued until the coil 12 is completely covback under the last wrap 14:. to. form what other suitable cutting implement. The gromet thus formedis then treated by the principal objects which the present invention hasinview are'z-to. pro vide an 'article of the character mentioned.

having even resistance throughout; to sim- Y plify the construction of devices of the cha'racter'mentioned, to reduce the cost of such construction; and to provide an article of the character mentioned having structurahgrou'ped packing members of difi'erent ftion 17 of the gromet,

y When the gromet is made int the modified form shown inFig. 6 of the drawings, the

loops 16 are produced by. more tightly wrapping the skein 11 and one of the coils '12 thereof, and by enlarging certain of the coils so that the loop "sections are extended from the .general circle of the completed. coil. When the loops are arranged substantially as shown in Fig. 6 of the drawings, .the skein -is' wound on the coil 12' to complete the relativelythickened body porshown in Fig. 3 of the drawings, are em-v ployed to seal the openingsformed in metal 20. The bolts 20 are engaged by nuts. 21,

and the gromet 22 is held between said plates 18 and 19 and awasher 2.3 which provides a bearing-surface for the nut 21. This-- gromet is pressed to the flattened condition shown best in Fig; 4 o fthe drawings."

3. As an article of manufacture, a gromet having a flat coil consisting of an unraveled fiber skein disposed to form a ring; and a covering for said ring formed by wrapping the loose end of said skein around the same to form successive spiral wraps, the outer wrap being'seated upon the finished end of the skein to bind the latter in position, said gromet being saturated with a permeating fluid impervious to water, said fluid having a non-setting, dense body for, avoiding the passage of water therethrough.

4. As an article of manufacture, a gromethaving a relatively large body portion, and a series of loops integrally connected with said body portion and extending laterally therefrom, said loops being adapted to form 1 auxiliary seals for the protection of areas WILLIAM A. YOUNG.
